Question

The decimal reduction time for endospores of Bacillus cereus in milk is 36.2 minutes at 95°C. How long should it take to reduce a population of 1015 endospores to 1 endospore?

Answer 1

Answer:

Time in hours

$\frac{543}{60} \\9.05$

Explanation:

Given

Decimal reduction time for endospores of Bacillus cereus in milk  $= 36.2$ minutes

Temperature at which bacillus endospores are reduced $= 95$°C

Population of endospores to be reduced $= 1015$

Targeted population of endospores $= 1$

So the total time taken to reduce population of 1015 endospores to 1 endospore is equal to

$36.2 * 15\\= 543$ minutes

Time in hours

$\frac{543}{60} \\9.05$
